A plastic pipe carries deionized water in a microelectronics clean room, and one end of it is capped. the water pressure is p0 = 60 psi, and the cap is attached to the end of the pipe by an adhesive. calculate the shear stress present in the adhesive.

Where the height of the cap is less than or equal to the radius of the bore of the plastic pipe then the ⇵⇵shear stress  is less than o equal to 60 psi.

Explanation:

Shear stress = F/A

where F = Applied force

A = Cross sectional area of the member experiencing the force

If the cap covers a section of the pipe of height, h then the area = 2πrh

Where the 60 psi pressure is acting on the pipe bore, we have P₀ = 60 psi  = F₀/A₀ where A₀ = area of pipe bore ≈ πr². Therefore if F₀ = F then we have

F₀/A₀ = F₀/πr² and F/A = F₀/2πrh = where h greater than or equal to 0.5×r then the shear stress is less than or equal to 60 psi
